Jefferson Andrés Lerma Solís (born 25 October 1994) is a Colombian professional footballer who plays as a defensive midfielder or centre-back for Premier League club Crystal Palace and the Colombia national team.

A youth product of Atlético Huila, Lerma played for three years in Colombia before joining Spanish side Levante on loan in 2016.

After being promoted to the main squad in January 2013, he made his professional debut on 30 March, starting in a 0–0 home draw against Millonarios.

[5] On the final match day, Lerma made his second direct contribution of the season, distributing an assist in a 1–1 home draw against Santa Fe.

[9] Although Lerma's goal secured an important victory, Huila failed to qualify for the Apertura's final phase after they lost away at Santa Fe and tied at home with Uniautónoma in their remaining matches, thus resulting in a 12th place finish.

Lerma suffered the first red card of his career on 2 August 2014, after receiving a second booking in the 45th minute during a Clausura match against Fortaleza.

[13] Overall, that season Lerma would establish himself as key integrant for Atlético Huila, which attracted the interest of European clubs such as Spanish side Levante.

[16] While disputing the 2016 Summer Olympics with Colombia on August 13, Lerma agreed to a one-year loan contract with La Liga club Levante.

On 21 August 2017, he made his return to the top-flight of Spanish football at home against Villarreal CF, where Lerma played the entire match as his team secured a 1–0 victory.

On 31 March, Lerma provided an assist for José Luis Morales' decisive equalizing goal against Girona away from home.

On 14 December 2019, Lerma provided a crucial assist for Dan Gosling's sole goal to help Bournemouth beat Chelsea 0–1 at Stamford Bridge.

[27] Lerma added his second assist of the season against Liverpool at Anfield, aiding Callum Wilson to lead 0–1 in the ninth minute.

He made another notable contribution on 27 September 2020, providing Arnaut Danjuma with an important assist to help win the match 1–0 against Norwich City.

In December, Lerma was charged with a biting offence relating to an act of violent conduct during a game against Sheffield Wednesday on 3 November 2020.

[28] On 12 December, Lerma provided a further assist for Dominic Solanke's 8th league goal, during Bournemouth's 5–0 thrashing over Huddersfield Town.

On 6 August 2022, Lerma scored Bournemouth's first goal of the season during Premier League opening match-day as his team went on to defeat Aston Villa 2–0.

[34] On 8 June 2023, fellow Premier League side Crystal Palace announced they had agreed personal terms with Lerma, and that he would join the club from 1 July.

[47] On 13 October 2020, Lerma scored his first international goal in a 2022 FIFA World Cup qualification fixture over Chile, which ended 2–2.

[48] For the 2021 Copa América, Lerma was excluded from Colombia's final squad by the newly appointed manager Reinaldo Rueda due to unspecified personal circumstances.

This discord could have impacted Lerma's position on Rueda's final list, which also excluded key players such as James Rodríguez and Radamel Falcao.

[51] In response to the speculation, the Colombian Football Federation issued a statement denying any rumors regarding Lerma's exclusion and confirmed that his absence from the final list was due to an unnamed personal situation that has yet to be disclosed.

[52] Lerma made his return to the Colombian national team on 7 October 2021, following a call-up from manager Reinaldo Rueda for the 2022 World Cup Qualifiers against Uruguay and Brazil.
